Problems solved by technology

Since the pitch of the track changes between wheels and tracks, and the pitch of the teeth on the hub is fixed, if the teeth on the hub are used to drive the track, it will cause some meshing parts to be out of alignment. will mesh, resulting in unstable operation

Abstract

A mobile wheel crawler device comprises a wheel crawler, two hubs and a crawler transformation mechanism. The two hubs are arranged on two sides of the wheel crawler respectively and closely cling to a friction bonding surface, the wheel crawler is driven to rotate by friction between the hubs and the friction bonding surface, and an accommodating space is formed between the two hubs. The crawler transformation mechanism is accommodated in the accommodation space and comprises a stretch driving device, stretch arms and first guide wheels arranged at one ends of the stretch arms, and the stretch driving device is used for driving the stretch arms to stretch or retract; after the stretch arms are stretched, the first guide wheels butt against the wheel crawler, and the wheel crawler is unfolded, so that the wheel crawler, the two hubs and the first guide wheels form a crawler-type travelling mode jointly; after the stretch arms are retracted, the wheel crawler is folded and clings to the hubs, so that the wheel crawler and the two hubs form a wheel-type travelling mode jointly. The mobile wheel crawler device drives the wheel crawler to rotate by friction, and has the advantage of running stability.

Description

technical field [0001] The invention relates to the field of mobile machinery, in particular to a wheel-track moving device. Background technique [0002] The walking modes of current wheeled vehicles and tracked vehicles are independent. That is, the vehicle is either in the crawler travel mode or in the wheel travel mode. Wheeled vehicles or mobile platforms have the characteristics of fast passage, flexible steering, and low movement resistance on flat roads. However, when walking on muddy roads or rough roads in the wild, the tires often slip, fall into pits and cannot move forward. Although crawler vehicles or mobile platforms can walk on muddy roads or uneven roads in the field and have the ability to overcome obstacles in the field, they are limited by the defects of slow walking, high resistance and high fuel consumption on normal roads. If the two motion modes are simply combined, that is, the vehicle or mobile platform is equipped with both wheels and tracks, the...
